Problems solved by technology

However, the old-fashioned crocodile clips can clamp the electric screw for a short time, but the crocodile clips are affected by the gravity of the wires, and once they are affected by vibration, external force, etc., they are easy to jump off and fall off. It must be re-tested. More seriously, if the crocodile clip falls in a bad position, it will cause voltage short circuit or grounding, which will directly cause secondary circuit failure and protection action

Abstract

The invention discloses a harmonic test tool, which relates to the field of power tools and solves the technical problems that the crocodile clips are easy to fall off during the harmonic test process in the prior art, interrupting the test, and having potential safety hazards. The harmonic test tool of the present invention The tools include a harmonic tester. The harmonic tester is connected to the electric screw through the collection box. There are several conductive wire groups arranged side by side on the collection box. One end of the conductive wire group is connected to the harmonic tester. electric screw. The invention is applied to harmonic testing.

Description

【Technical field】 [0001] The invention relates to the field of electric tools, in particular to an electric testing tool. 【Background technique】 [0002] The harmonic test mainly collects three-phase AC voltage and three-phase AC current. When connecting to the three-phase AC voltage, due to the complexity of the on-site voltage terminals, it is necessary to use the fixing method of alligator clips to clamp the electric screw for connection. However, the old-fashioned crocodile clips can clamp the electric screw for a short time, but the crocodile clips are affected by the gravity of the wires, and once they are affected by vibration, external force, etc., they are easy to jump off and fall off. It must be re-tested. More seriously, if the alligator clip falls in a bad position, it will cause voltage short circuit or grounding, which will directly cause secondary circuit failure and protection action. 【Content of invention】 [0003] The technical problem solved by the inv...
